How do I move my calibre library from one computer to another?
How do I move my calibre data from one computer to another?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Simply copy the calibre library folder from the old to the new computer. You can
find out what the library folder is by clicking the calibre icon in the
toolbar. The very first item is the path to the library folder. Now on the new
computer, start calibre for the first time. It will run the Welcome Wizard asking
you for the location of the calibre library. Point it to the previously copied
folder. If the computer you are transferring to already has a calibre
installation, then the Welcome wizard wont run. In that case, right-click the
calibre icon in the tooolbar and point it to the newly copied directory. You will
now have two calibre libraries on your computer and you can switch between them
by clicking the calibre icon on the toolbar. Transferring your library in this
manner preserver all your metadata, tags, custom columns, etc.
Note that if you are transferring between different types of computers (for
example Windows to OS X) then after doing the above you should also right-click
the calibre icon on the tool bar, select Library Maintenance and run the Check
Library action. It will warn you about any problems in your library, which you
should fix by hand.
You can export all calibre data (books, settings and plugins) and
them import it on another computer. First let use see how to export the data:
* Right click the calibre icon in the main calibre toolbar and select
:guilabel:`Export/Import all calibre data`. Then click the button labelled
:guilabel:`Export all your calibre data`. You will see a list of all your
calibre libraries. Click OK and choose an empty folder somewhere on your
computer. The exported data will be saved in this folder. Simply copy this
folder to your new computer and follow the instructions below to import the
data.
* Install calibre on your new computer and run through the Welcome Wizard, it
does not matter what you do there, as you will be importing your old
settings in the next step. You will now have an empty calibre, with just
the :guilabel:`Getting Started` guide in your library. Once again, right
click the calibre button and choose :guilabel:`Export/Import all calibre
data`. The click the button labelled :guilabel:`Import previously exported
data`. Select the folder with the exported data that you copied over
earlier. You will now have a list of libraries you can import. Go through
the list one by one, and select the new location for each library (a
location is just an empty folder somewhere on your computer). Click OK.
After the import completes, calibre will restart, with all your old
libraries, settings and calibre plugins.
.. note:: This import/export functionality is only available from calibre
version 2.47 onwards. If you have an older version of calibre, or if you
encounter problems with the import/export, you can just copy over your
calibre library folder manually, as descibed in the next paragraph.

by clicking the calibre icon on the toolbar. Transferring your library in this
manner preserver all your metadata, tags, custom columns, etc.
.. note:: A calibre library is just a folder which contains all the book files and their metadata. All the metadata is stored in a single file called metadata.db, in the top level folder. If this file gets corrupted, you may see an empty list of books in calibre. In this case you can ask calibre to restore your books by doing a right-click on the calibre icon in the toolbar and selecting Library Maintenance->Restore database
The list of books in calibre is blank!
